Let’s look at the 9 steps to legit check the Sulfurs.

How to spot fake Yeezy Boost 350 V2 Sulfur

The quickest way to spot fake Yeezy Sulfur is by examining the size tag and the boost sole.

Often, counterfeit Yeezys display incorrectly positioned and weighted text on the tag, and the boost sole pellets are wrongly placed and shaped.

1. Barcode scan

Remember, each Yeezy has a distinct barcode corresponding to a specific combination of:

  • Colorway: SULFUR (FY5346)
  • Style: 350 V2
  • Size: Ranging from 4 to 17 (US)

1.1. How to scan

  • Open the Legit Check App.
  • Tap Barcode scanner.
  • Point the barcode to your box.
  • Verify the results.

The outcome requires careful analysis.

Use your judgment to evaluate matches that validate the authenticity of your Yeezy Boost V2 Sulfur.

1.2. Authentic results

  • The barcode matches the shoes:
  • Yeezy Boost 350 V2 Sulfur, FY5346, Size 9.5 (US)

If the barcode matches multiple Google confirmation points, the box is likely authentic.

Authentic box doesn’t always mean authentic sneakers; they could be swapped by replica sellers.

1.2. Fake results

  • No results are shown for the barcode.
  • Missing style-code, model, size, and colorway.
  • Authentic: A perfect match requires both size and colorway to align with box details.

If in doubt, refer to our detailed barcode scan guide.

2. Size tag


  • Authentic: Features smaller and thicker text. The spacing between each letter is constant.
  • Fake: The text appears larger, thinner, and often the spacing between the letters is inconsistent.

2.2. “US UK FR JP CHN”

  • Authentic: The text has a thicker appearance.
  • Fake: Appears thinner in contrast.

2.3. Date of Manufacturing

  • Authentic: A thinner print for the date, for example, “02/20”.
  • Fake: The print looks overly thick.

2.4. MALE/MÂLE Text

  • Both authentic and replica Yeezy Boost V2 Sulfur can have or not have the MALE/MÂLE inscriptions. This aspect alone shouldn’t be used as a determinant of authenticity.

2.5. “adidas ®” Text

  • Authentic: Features thicker inscriptions and there’s clear space between “adidas” and the “®” symbol.
  • Fake: The text is usually too thin and may sometimes have “adidas” in contact with the “®” symbol.

2.6. APC Number Print

  • Authentic: The APC number (indicating the manufacturing factory) is thicker.
  • Fake: The number appears thinner.

3. Box label

3.1. Versions

Yeezy V2 sneakers are released in two main versions: US & International.

  • US Version
    • Features three sizes on the label: US, UK, and F.
    • The US size is prominently displayed, whereas the UK and F sizes are printed smaller beneath it.
  • International Version (EU + Canada)
    • Displays the sizes for six countries: US, UK, F, D, J, and CHN.
    • All six size listings are printed at an equal font size on the label.

3.2. Serial numbers

  • US Version: The serial number should typically end with V02 or V03.
  • International Version (Canada + EU): The serial number should end with V10.

For example, a US version label that ends with V10 or an international version ending with V02/V03 is a red flag.

  • The fake US label above has the “V10” inscription.
  • It should have a “V02” or “V03” serial number to be authentic.

4. Lacing

Right Shoe:

  • Authentic – From the wearer’s perspective, the right lace should be under the left lace.
  • Fake – The laces are attached the other way around. We call them “inverted laces”.

Left Shoe:

  • Authentic – From the wearer’s perspective, the left lace should be under the right lace.
  • Fake – Has “inverted laces”.

Let’s take a look at this image to better understand this:


  • On the right shoe, from the wearer’s view, the right laces should be beneath the left laces.
  • On the left shoe, from the wearer’s view, the left laces should be beneath the right laces.
  • Deadstock pairs should have this specific factory lacing pattern.


  • The laces do not follow the authentic pattern, often being “inverted”.
  • On counterfeit Yeezys, deviations from the standard lacing pattern are common.

5. Boost

5.1. Best replica


  1. The boost is bubbly, soft, and has a specific texture to it.
  2. The pellets on the boost are consistent in shape and evenly spaced out.
  3. Boost sole has a distinct feel and is renowned for its comfort.


  1. The boost is often stiffer and doesn’t have the same soft texture as the authentic pairs.
  2. Pellets on the fake boost sole might be irregular in shape and unevenly spaced.
  3. Upon closer inspection, the boost on counterfeit pairs may show visible discrepancies in texture and feel compared to authentic pairs.

5.2. Mid replica


  • Pellets appear more randomized in placement.
  • Pellets have a smoother texture.


  • Pellets often appear mathematically aligned.
  • Rougher texture on the pellets.

5.3. Low replica

In the image provided, we showcase another example of the counterfeit Yeezy Sulfur boost sole.

6. Shape


  • Wider opening at the tongue area on the sockliner.
  • Balanced shape, not too narrow or too wide.


  • Tongue area tends to be narrower, especially at the sockliner’s opening.
  • Some fakes may also present an opening that’s too wide.

7. Stitching


  • Stitching in the middle is shorter in length.
  • The stitches appear thicker.


  • Middle stitching is noticeably thinner.
  • The stitches are longer than those on the authentic pair.

8. Toe box


  • Toe box is less curvy and doesn’t have a bumpy appearance.
  • It retains its original structure without looking over-inflated.


  • The toe box is noticeably curvier.
  • Often has an over-inflated appearance, making it look bulkier than it should.

9. Insole

9.1. Rear


  1. The Adidas Trefoil logo has a significantly deeper embossment, evident in the shadows reflecting the depth.
  2. Characters in the “Adidas” text are finer and thinner.
  3. Less distance between the “Adidas” text and the outline, creating a more compact look.
  4. The ® engraving matches the depth of other characters on the logo.


  1. The logo embossment isn’t as deep as on the authentic.
  2. Characters in the “Adidas” text are noticeably thicker.
  3. There’s an evident space between the “Adidas” text and the outline.
  4. The letter R in the ® engraving is larger than it should be.

9.2. Front

Now, let’s check the adidas x YEEZY logos.


  • The “adidas” and “YEEZY” texts have letters that are bold and thick.
  • Both texts are consistent in font weight and size.


  • The letters in the “adidas” and “YEEZY” texts appear too thin.
  • Lack of consistency and boldness in the font compared to the authentic pair.

9.3. Serial number


  • Proper thickness and spacing in the serial number text.
  • Clear dash character between numbers.


  • Thicker serial number text, causing reduced spacing.
  • Squeezed appearance of the dash character.

Shortlist: Legit check your Yeezy Sulfur

  1. Scan the barcode: the style-code, color, model, and size must match your pair.
  2. Examine the shoe’s shape, ensuring the tongue isn’t excessively long.
  3. Observe the lacing pattern: on the right shoe, the right lace should be underneath, while on the left shoe, the left lace should be underneath (from a top-down perspective).
  4. Review the size tag for any irregularities, as highlighted in our Yeezy Sulfur comparison.
  5. Check the toe box; counterfeit versions often have a more pronounced arch.
  6. Assess the tongue’s shape, especially the tongue area, which can be either insufficiently or overly curved in fakes.
  7. Examine the boost sole, noting that fake ones often have misshapen pellets.
  8. Inspect the central stitching; replicas typically have longer, thinner stitches.
  9. Evaluate the insole’s text, as counterfeit Yeezys often display improper font-weight.
